A girl travels 5 blocks west, 4 blocks north, then 7 blocks east. It asked to solve for the magnitude of her displacement and I got 4.472135955 blocks, which was correct. The next part of the problem however asks to "Find the direction (measured from due east, with counterclockwise positive) of her displacement. Answer in units of degrees." I just began physics last and my teacher didn't go over this. I know the displacement is northwest, but I don't know how to find the degrees of it. Thank you very much!
